IPC: A63F3/06
Filed: 1988-04-27
Abstract: A color-changeable toy having a toy body to which a quasireversible thermochromic material is applied in a pattern. This material stably holds either of two coloured states in a range of ordinary room temperature. However, the material reversibly changes to one of the states above this range and to the other below this range. Thereby, by using commonly available heat and chilling sources such as ice, hot water or breath, one of the colours can be selected. A breath blow pipe can be used in conjunction with the toy and have an external appearance associated with that of the toy, e.g. gun and soldier. One of the "coloured" states can be colourless to permit an underlying coloured layer to show.

Abstract: The invention provides for the production of fibre reinforced metal materials by feeding the fibres (5) through an entry port (6) in a receptacle (4) and into molten metal (8) which is contained under pressure in the receptacle (4) as illustrated in Fig. 1. The temperature and pressure of the molten metal (8) are controlled so that the composite material (11) can be withdrawn via an exit port (12) of the receptacle (4). Pressure is maintained by supplying a gas, such as nitrogen, through the orifice (13) at a pressure of 14-105.5 kgcm<-2> which will overcome surface tension for metal infiltration. The temperature is maintained at the correct temperature for coating, ideally 650 - 750 DEG C, by electric heaters (7). Preferably means are provided for controlling at least one of the rate of feed of the fibres and the temperature and pressure of the molten metal to effect solidification of the molten metal in the exit port. The entry port may be caused to reciprocate relative to the fibres passing therethrough. The fibres used are generally ceramic, eg alumina, silicon carbide or carbon but may also be metal, eg steel wire. The fibres may be used in the form of individual filaments, bundles or tows, or in woven form. <IMAGE>

Title: Emergency evacuation
Inventor: MASCARENHAS EVERARD JOSEPH
IPC: G09F19/22
Filed: 1991-12-11
Abstract: An audio signal source 48 feeds loudspeakers 68, 70 of a stereo pair via amplitude modulators 60, 62 which are supplied with respective modulation signals 56, 58. Loudspeaker 68 is therefore fed with an audio signal the amplitude of which repeatedly cycles through the sequence: short rise-time/long fall-time, and loudspeaker 70 is simultaneously fed with an audio signal the amplitude of which repeatedly cycles through the sequence: long rise-time/short fall-time. The effect is of stereophonic sound repeatedly moving from loudspeaker 68 to loudspeaker 70, and this is used in an arrangement for guiding personnel during evacuation from buildings etc. The stereophonic effect can be enhanced by the so-called "wide stereo" effect, employing attenuators 82 and 84 and amplifiers 78 and 80 to add a portion of the signal in each channel in antiphase to the signal in the other. <IMAGE>

Abstract: A database with sequentially stored records is subjected to a batch processing operation to generate index files, each containing addresses for the records in a certain category as determined by selection and conditional filtering operations. The conditional filtering operations use set conditions which conditionally restrict the entry of addresses to the index files so that less memory is required and processing speed is improved. When data is being accessed either the full record may be retrieved from the database or alternatively an index file may be accessed for quick and efficient retrieval of the relevant information. <IMAGE>
Patent GB-912984-A (GB)
IPC: G01F23/24
Abstract: 912,984. Indicating liquid levels. MINNEAPOLISHONEYWELL REGULATOR CO. Dec. 24, 1958, No. 41729/58. Class 123 (1). [Also in Group XXX] In a fluid-level indicator comprising a modified bridge circuit 15 with a sensing arm formed by a negativetemperature coefficient resistor 40, which can be mounted, e.g. in a fluid container 49 at such a level as to be able to unbalance the bridge whenever the fluid passes that level, a compensating element 48, consisting of a second negative-temperature coefficient resistor 45 sealed in an air-filled envelope, is incorporated in the bridge so that it can operate effectively even when dealing with relatively hot liquid and cold air. The bridge comprises impedance arms 20, 30, 35 and the resistor 40 which, when immersed in liquid, has a voltage drop across it to maintain the bridge balanced so that no current flows from a point 26 to a point 21 through a detector arm having a relay 55 and a rectifier diode valve 56. When the liquid level falls below the resistor 40 the voltage across the latter, now in air, decreases to unbalance the bridge so that current, flowing in the detector arm, actuates the relay 55. The compensating circuit comprises a diode 50 which, irrespective of the amount of current flowing through it, provides a substantially constant voltage drop between the point 26 and a point 31 between an impedance 30 and the sensing resistor 45. The compensating resistance 45 at substantially the same temperature as the resistor 40 when it is immersed in liquid, raises the potential of the point 31 and thus the higher potential at the more positive side 26 of the diode 50 by an amount equal to the voltage drop across the resistor 40 in air. This compensates for the otherwise lack of potential difference between the points 21, 26 when the voltage across the resistor 40 does not drop sufficiently, upon emerging from the liquid, to actuate the relay 55. The potential drop across the diode may be adjusted by selecting a diode of the correct impedance or by inserting several diodes in series until the voltage level of the point 26 is properly located with respect to the point 31 that is so that it is higher or lower than the point 21 whenever the resistors 40, 45 are in air or immersed in liquid respectively.
